11g的RMAN duplicate 可以通过Active databaseduplicate和Backup-based duplicate两种方法实现。这里的测试使用的是Active databaseduplicate,因为Active database duplicate 功能强大,不需要先把目标数据库进行rman备份,只要目标数据库处于归档模式下即可直接通过网络对数据库进行copy,且copy完成后自动open数据库。这对于大数据特别是T级别的数据库来说优点非常明显,复制前不需要进行备份,减少了备份和传送备份的时间,同时节省备份空间。下面来进行具体的duplicate操作。
监听,口令文件配置,pfile配置,创建clone库相关目录等过程同基于备份的RMAN复制一样
